BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates generally to a compound that can be usedas a dispersing agent or suspending agent in compositions. The compoundcan include a guar gum backbone that has selected groups attached to thebackbone.

B. Description of Related Art

Cosmetic compositions come in a wide variety of colors or shades. Thisvariety is often exhibited in products such as lipsticks, eyeliners,mascara, and blushes. Colorants such as pigments can be used to createthese different colors or shades.

A problem associated with the use of colorants is that they tend toagglomerate together in a composition. This agglomeration can cause thecolor of the composition to appear blotchy. One attempt to solve thisagglomeration problem is to either treat the surface of the colorants oradd a compound to the composition that interacts with the colorant tomore efficiently disperse the colorant throughout the composition.Although these type of treatments and compounds have been shown todecrease agglomeration, such treatments and compounds oftentimesinefficiently disperse such colorants. This can cause the composition tohave a streaky or non-homogenous color appearance.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The guar gum containing compounds of the present invention have a guargum backbone with selected R groups attached to the backbone. Guar Gumis a glactomannan polymer that can be extracted from the seed of theleguminous shrub Cyamopsis tetragonoloba. This plant is typicallycultivated in India, Pakistan, and southwestern U.S. The CAS registrynumber for guar gum is 9000-30-0. Guar gum is commercially availablefrom a variety of sources (e.g., Tic Gums—Belcamp, Md., and RhodiaInc—Cranbury, N.J.). Non-limiting examples of R groups include —H, —OH,an alkoxy group, an acyloxy group, an amino group, an amido group, asulfate group, a sulfonate group, a phosphate group, a phosphonategroup, or a silicone group. The selected R groups can modify or providedesired characteristics to the guar gum compound. By way of exampleonly, some desired characteristics include dispersion and/or suspensioncapabilities when the modified compound is used in a given compositionor a phase of a composition.

When the compounds of the present invention are used as a dispersionagent, they can be used to disperse colorants or other solid ingredientsefficiently throughout the composition or a phase of the composition(e.g., a hydrophobic phase of a water-in-oil or oil-in-water emulsion).An advantage of having efficient dispersion of a colorant is that it canreduce the appearance of undeveloped colors in the composition. Thecomposition can have a homogenous color appearance. Because of theefficient dispersion, more colorant can be added to the compositionwithout affecting the stability of the composition which can be usefulin obtaining a true or more intense, vivid, or vibrant color. When usedas a suspending agent, the compounds can effectively modify theviscosity of the composition. For instance, the compounds can be used toincrease the viscosity of a composition to achieve a desired rheologicalcharacteristic.

These and other aspect of the invention are described in furthernon-limiting detail below.
